The Case of the Diamond Dog Collar

First Kids Mysteries

When a big fat diamond disappears from first-dog Hooligan’s new collar, White House kids Cammie, Tessa and Nate have to find it – or risk causing yet another international incident. Meanwhile, Hooligan is doing great in puppy school with celebrity dog trainer Julius Mormora, and glamorous visitor Madeline Kootoor is serving as “cameraman catnip” for the White House press corps. From a near helicopter crash on the South Lawn to a wild diamond chase on the White House grounds – “The Case of the Diamond Dog Collar” is a mile-a-minute caper with more twists, turns and laughs than a labradoodle’s bad haircut.
